Best head-size for FWB124??

[garczar6]

I recently purchased 12 tins of JSB 8.4's. Six are 4.52 and six 4.53. Anyone have any take on which size a 124 might like? I'm going to take half to sell/trade at Malvern show and would like an idea of which to keep.   Thanks

I believe each gun is different. It may prefer 4.51. Impossible question to answer without testing your particular rifle. Unless you're just taking a general consensus, and then making  a guess as to which size will work in your rifle, actual testing needs to be done.
 Good luck, I wish I was able to attend the Malvern show. Report back.

A guess is all that can be made.  But FWB barrels often prefer smaller head size pellets, 4.51 or even 4.50mm.  The only way to know is to try out different pellets.
